I need you to understand that this is a fairly big task even for many experienced people and it will take an awful lot of work...if your up for it I'll give you all the advice I can. Be prepared to get frustrated, a lot of work is tedious and in some cases mind numbing.

Just another couple of quick questions...do you have a shop or a garage? AND Are you prepared to strip the car? With the type of rust you have (C Pillar, quarter panels etc.) if you strip the car you can get rid of all the rust before you spend money on material and paint over top of it...leading to starting over again or what happens all to often, giving up in frustration.
